ADR mark - rose quality guarantee
The insignia of roses - the main assistants in choosing garden princesses. And one of the most reliable is the symbol of German quality ADR (Allgemeine Deutsche Rosenneuheitenprufung), which is assigned to roses after a rigorous assessment. He distinguishes especially persistent and richly colored roses.
Everyone who has faced the difficult task of choosing roses from hundreds, thousands of varieties is well aware of the horror of the "huge assortment". Today you can buy plants of domestic and foreign selection, various nurseries and producers, and the number of varieties with different shades of color and decorative "details" makes the choice very difficult. But when buying a rose, you also need to remember endurance, reliability, winter hardiness ... Not the last characteristic is a tendency to diseases, in particular powdery mildew, and pests.
And special insignia are designed specifically to facilitate the task of choice. One of the most reliable reference points is the German quality mark - ADR. It is awarded to selected roses that have undergone a comprehensive assessment and lengthy trials. And even if he doesn’t guarantee that you will succeed with a particular rose - there are too many subjective factors, including the specific conditions of your plot, which affect the result - but he perfectly fulfills his main task: it makes it easy to “identify” roses with the best reliability characteristics .
What does the ADR label for a variety name mean?
Let's try to figure out what the ADR labeling of the variety name means and by what parameters roses are marked.
The ADR marking, which can be deciphered as the “General German Certification of Varietal Roses”, is the distinguishing mark of the German Rose Growers Society, which is considered one of the most reliable signs of rose quality and is highly regarded throughout the world. The general test of roses was initiated more than sixty years ago by the legendary Wilhelm Cordes, and over time, the ADR quality mark became truly a cult. Some even call it the most stringent means of controlling the quality of newly introduced varieties. Modern roses are tested, although since 2006 it has been awarded to some nostalgic roses and modern varieties of old roses.
Evaluation of roses is carried out by a special working group of the Community of German Nurseries, Test Gardens and the best rose growers. The ADR sign takes into account three key varietal parameters:
- winter hardiness;
- lush color;
- resistance to diseases.
But everything is not so simple: in fact, there are more criteria and the assessment covers all possible characteristics.
What is taken into account when evaluating ADR?
All roses are rated according to points, while the indicators are far from equal in value. For example, resistance to fungal diseases (30 maximum points) makes the greatest contribution to the “rating” of roses. And it is precisely the greatest stability that is the most significant sign of roses marked with a quality mark, and not at all winter hardiness, as we consider. The decorativeness of the rose (the balance of the crown, the appearance of the bush, the foliage, the shape and color of the leaves, the number of flowers, their sizes, etc.) are estimated at a maximum of 20 points, the stability of the color of the flowers, the duration of flowering and the shape of the flowers bring the rose only 10 points. And winter hardiness, aroma and growth form - only 5.
But do not assume that such a point distribution means that roses are not at all very frost-resistant. Criteria, despite the distribution of points, are also divided into key and secondary, and the number of sub-criteria allows you to evaluate the rose really comprehensively. After all, experts also take into account resistance to drought, heat, precipitation, the shape of the bud, the opening of a flower and the preservation of beauty after full disclosure, whether the rose discards faded blossoms on its own and dozens of other factors.
The ADR mark is awarded only to the most enduring roses, which pass a long assessment and many years of testing. In order to receive an insignia, a variety must score at least 75 out of 100 possible points. Roses are subjected to long-term testing, planting them in different regions of Germany with milder and harsher winters for 3 years, without treating plants with any chemical methods of protection against pests and diseases. Moreover, the tests are carried out in 11 gardens scattered throughout Germany, under strict supervision. Constant inspections, flowering monitoring and development monitoring for such a long time allow us to judge the characteristics of the rose and its shortcomings.
Passing the test and getting the ADR sign is not so simple. And evidence of this is the fact that only every 10-12 rose from the tested really passes the test and is marked with this sign. And even successfully evaluated roses continue to be monitored, tested and undergo additional checks. In many ways, the award of the ADR sign is similar to Michelin stars in the restaurant and hotel business: the award is received only for impeccability, and they can lose it at the slightest deviation, literally in the blink of an eye.
This is one of the best guidelines that helps both experienced and novice growers not to get lost in this sea of rose varieties and choose the best shrubs. And most importantly - to rid yourself of disappointments and worries, not in vain to spend money and really get what you want with minimal risk of failure. Assessing the rose for health, reliability, durability, and unpretentiousness, the ADR sign does not forget about the main thing - aesthetic characteristics, attractive varieties.
